[Cuis] Status of Morphic?

[Phil (list)]

Hannes,

Sorry for the delay... it's taken me longer than expected to get back to
it.  I really don't have any simple examples of porting as my stuff is
fairly involved (i.e. drawing and keyboard handling as part of a larger
OpenGL project etc.)  However, I do have more specifics re: what needed
to be done.

Morphic (continuous) animation

previously:
#step

now:
#stepAt: (just rename #step to #stepAt: milliseconds)
#wantsSteps (^true)

Notes:
1) If this change isn't made, you may get what appears to be animation,
but it's just the morph redrawing after damage.
2) Be sure to call #truncate on bounds etc. if your code can't handle
floats.
3) I used to have several direct Morph subclasses, but it appears that
they now need to be RectangleLikeMorph subclasses to maintain similar
behavior.



Keyboard focus handling

previously:
#handlesKeyboard (^ true)
#keyboardFocusChange: (call any code needed to deal with getting/losing
focus such as drawing a focus indicator)
#handleKeystroke: (when morph has focus, will receive keystroke)

now:
This is my best guess... are there any examples of working Morphs that
deal with keyboard focus but do *not* have text morphs?
#handlesKeyboard (no change)
#handlesMouseOver: (^true to get #mouseEnter: & #mouseLeave:)
#mouseEnter: event
	event hand newKeyboardFocus: self
#mouseLeave: event
	event hand newKeyboardFocus: nil
#keyStroke: event (receives the keystroke when focused, some event
accessors no longer exist)

Thanks,
Phil
